It is an objective of the present invention to reduce weight further in a wheel disk 1 for vehicle. A hat portion 20 of the wheel disk 1 for vehicle includes an annular top portion 21, an inner peripheral portion 22 and an outer peripheral portion 23. The inner peripheral portion 22 connects the top portion 21 and a hub attachment portion 10. The outer peripheral portion 23 connects the top portion 21 and welding flanges 30 and connects the top portion 21 and the window-forming flanges 40. The welding flanges 30 are welded to an inner periphery of a wheel rim 2. Windows 5 are formed between the window-forming flanges 40 and the inner periphery of the wheel rim 2. The outer peripheral portion 23 of the hat portion 20 includes first regions 231 and second regions 232 alternately in a circumferential direction. The first regions 231 are connected to the welding flanges 30 and the second regions 232 are connected to the window-forming flanges 40. Connecting portions 45 connecting the second regions 232 and the window-forming flanges 40 are protruded outward in an axial direction with respect to corresponding portions 231a of the first regions 231.
